Abstract : A Cohen-Kaplansky domain CK domain R is an integral domain where every nonzero nonunit element of R is a ¯nite product of irreducible elements and such that R has only ¯nitely many nonassociate irreducible elements. In this paper, we investigate seminormal CK domains and obtain the form of their irreducible elements. The solutions of a system of diophantine equations allow us to give a formula for the number of distinct factorizations of a nonzero nonunit element of R, with an asymptotic formula for this number.
